4201-B “STOL BOWL” nose bowls

Builders,

Just a 12 hours to go before departure for Corvair College #44 At the Zenith Aircraft Factory, but we are still prepping regular parts to be shipped by SPA while we are on the road.

.

.

Above, two STOL bowl, production parts. One is for Florida Zenith builder Ramesh Nori, the other one is yet to be adopted. If you would like to be the new owner, all you have to do is call Lisa at SPA: 904-626-7777, place the order, and it will be shipped on Thursday.  Care and feeding is easier than adopting a puppy, plus, your STOL bowl will not ruin your carpet nor chew shoes.

.

Looking forward to seeing many of you at the College.

Night Run: Carb and Intake testing

Builders,

A quick look at Sunday night, outside my hangar. Dan Weseman was looking for an intake design and a Carb orientation and model, specifically for Corvair powered Panthers with tricycle gear. Tonight was the test run, and it turned out amazingly good.

.

.

Above, a look at the back of my test stand; Notice it is now sporting two lab grade 5 wire O2 driven Air/Fuel meters.  The test question was essentially this: If a Rotec TBI is turned 90 decrees, will it still have excellent mixture distribution to both sides of the engine. The answer is yes. This was the largest spread under power, .3 on the air/fuel ration. That is as good as carbureted engines get.

.

Above, a look at the Rotec on the manifold. It started and ran exceptionally well.

.

After tests, Dan Rachel and I ate dinner at their place and talked about a lot of stuff, ranging from airport business to the new “Ford vs Ferrari” movie. It was a real nice end to a productive weekend.

Hat, Fez or Pail? Your Friday the 13th Corvair question.

.

Builders :

Your Friday the 13th, Full moon, question: 

Do you vote for “The Hat of Power” , “The Fez of Kamal” or “Pail of Professionalism”?  Does head wear make the man? Would you be confident enough to rock one of these styles? Who is the biggest badass if the land of Corvairs? Here your franchise counts, vote and give your reason in the comments.

.

.

Above,  Kevin Purtee When you’re a badass like Kevin, any hat you wear is “The Hat of Power.” To understand more, read: Kevin Purtee and “The Hat of Power”

Above, a Fez and wrap-around shades are the hallmarks of the man I often introduce as  “Kamal Mustafa, my attorney”. This is Ken “Adonis” Pavlou advises aviators: “Life is short, Live Large”

.

The whole point of homebuilding is to get you to the self reliant mindset, where you follow positive flying examples rather than listen to people who still live in a world of doubt and fear.  You deserve to have your own adventures like Ken’s: 1,500 mile Corvair College flight in a 601XL ,

.

.

Above, Witness “The Pail of Professionalism” (it is covered in Unicorns and rainbows)  If there is a Renaissance  Man in Corvairs, it is Dan Weseman. When it comes to stick and rudder flying, he has few peers. He learns things at an astounding rate. (Frankly, if you are a troglodyte it’s annoying) He is a born motorhead, as evidenced by this: SPA / Weseman 3.3 Liter Corvair now running and if you want to read about the last word in Corvair Performance, check this out: Understanding Flying Corvairs Pt. #2, Hardest working engine

.

Make your voice heard! Polls close after this weekend, and just like cook county in 1960, feel free to vote twice.

Safety Alert Reference Page

Builders:

This page is the permanent site where I will keep all the “Safety Alerts” which I have published for Corvair Flight engines. This will be updated as required. It’s current date of revision is:

.

September 12th, 2019

.

I am putting it out so builders doing inspections on Corvair powered planes can come to one location and check the applicability of each issued “Safety Alert” to their particular aircraft.  The date above should be included in the log book entry of the inspection, stating the plane is in compliance with Alerts issued by that date.

.

Please note: We are about to issue a “2019 Maintenance, Operations, and procedures manual” Which is a 75 page, direct handbook for these topics. It is what a builder will have in his hand during maintenance. Because it is a physical handbook, this page will serve as an access point to updates to the manual.

.

I use the term “Safety Alert” and calling for “Suggested Action” because Corvairs are experimental engines, and as such, do not have Airworthiness Directives and Service Bulletins in the same form as certified engines do. I cannot require any builder to take any action, I can only appeal to his better judgment by making a serious recommendation. Airworthiness Directives are only issued by the federal government, and Service Bulletins are issued by certified part manufacturers, thus the difference in the Safety Alert.

This said, I appeal to builders to follow this recommendation. The most frequent form of push back on suggestions of this kind is a builder who is myopically looking at his one plane and making a conclusion based on his impression of his own plane. Conversely I get to see all the data, understand the extenuating or aggravating conditions, I had world class training in statistical decision making at Embry-Riddle, and I always further consider what still works, not just looking at what broke.  I am not a genius, but for the above reasons, my recommendations on Corvair flight engines carry more weight than those of one guy with a flying plane, even a well intentioned one.
